Validation of the Physician-Pharmacist Collaborative Index for physicians in Malaysia

Sellappans R, Ng CJ, Lai PS

Int J Clin Pharm, 2015 Dec;37(6):1242-9.
PMID: 26408408 DOI: 10.1007/s11096-015-0200-6

BACKGROUND: Establishing a collaborative working relationship between doctors and pharmacists is essential for the effective provision of pharmaceutical care. The Physician-Pharmacist Collaborative Index (PPCI) was developed to assess the professional exchanges between doctors and pharmacists. Two versions of the PPCI was developed: one for physicians and one for pharmacists. However, these instruments have not been validated in Malaysia.
OBJECTIVE: To determine the validity and reliability of the PPCI for physicians in Malaysia.
SETTING: An urban tertiary hospital in Malaysia.
METHODS: This prospective study was conducted from June to August 2014. Doctors were grouped as either a "collaborator" or a "non-collaborator". Collaborators were doctors who regularly worked with one particular clinical pharmacist in their ward, while non-collaborators were doctors who interacted with any random pharmacist who answered the general pharmacy telephone line whenever they required assistance on medication-related enquiries, as they did not have a clinical pharmacist in their ward. Collaborators were firstly identified by the clinical pharmacist he/she worked with, then invited to participate in this study through email, as it was difficult to locate and approach them personally. Non-collaborators were sampled conveniently by approaching them in person as these doctors could be easily sampled from any wards without a clinical pharmacist. The PPCI for physicians was administered at baseline and 2 weeks later.
MAIN OUTCOME MEASURE: Validity (face validity, factor analysis and discriminative validity) and reliability (internal consistency and test-retest) of the PPCI for physicians.
RESULTS: A total of 116 doctors (18 collaborators and 98 non-collaborators) were recruited. Confirmatory factor analysis confirmed that the PPCI for physicians was a 3-factor model. The correlation of the mean domain scores ranged from 0.711 to 0.787. "Collaborators" had significantly higher scores compared to "non-collaborators" (81.4 ± 10.1 vs. 69.3 ± 12.1, p < 0.001). The Cronbach alpha for the overall PPCI for physicians was 0.949, while the Cronbach alpha values for the individual domains ranged from 0.877 to 0.926. Kappa values at test-retest ranged from 0.553 to 0.752.
CONCLUSION: The PPCI for physicians was a valid and reliable measure in determining doctors' views about collaborative working relationship with pharmacists, in Malaysia.
Fulltext Challenges faced by primary care physicians when prescribing for patients with chronic diseases in a teaching hospital in Malaysia: a qualitative study

Sellappans R, Lai PS, Ng CJ

BMJ Open, 2015 Aug 27;5(8):e007817.
PMID: 26316648 DOI: 10.1136/bmjopen-2015-007817

OBJECTIVE: The aim of this study was to identify the challenges faced by primary care physicians (PCPs) when prescribing medications for patients with chronic diseases in a teaching hospital in Malaysia.
DESIGN/SETTING: 3 focus group discussions were conducted between July and August 2012 in a teaching primary care clinic in Malaysia. A topic guide was used to facilitate the discussions which were audio-recorded, transcribed verbatim and analysed using a thematic approach.
PARTICIPANTS: PCPs affiliated to the primary care clinic were purposively sampled to include a range of clinical experience. Sample size was determined by thematic saturation of the data.
RESULTS: 14 family medicine trainees and 5 service medical officers participated in this study. PCPs faced difficulties in prescribing for patients with chronic diseases due to a lack of communication among different healthcare providers. Medication changes made by hospital specialists, for example, were often not communicated to the PCPs leading to drug duplications and interactions. The use of paper-based medical records and electronic prescribing created a dual record system for patients' medications and became a problem when the 2 records did not tally. Patients sometimes visited different doctors and pharmacies for their medications and this resulted in the lack of continuity of care. PCPs also faced difficulties in addressing patients' concerns, and dealing with patients' medication requests and adherence issues. Some PCPs lacked time and knowledge to advise patients about their medications and faced difficulties in managing side effects caused by the patients' complex medication regimen.
CONCLUSIONS: PCPs faced prescribing challenges related to patients, their own practice and the local health system when prescribing for patients with chronic diseases. These challenges must be addressed in order to improve chronic disease management in primary care and, more importantly, patient safety.

Fulltext In vitro activity of aminoglycosides, ureidopenicillins and cephalosporins against P. aeruginosa isolated in Kuala Lumpur

Ngeow YS, Puthucheary SD, Lai PS

Med J Malaysia, 1985 Sep;40(3):196-201.
PMID: 3939567

170 clinical isolates of Pseudomonas aeruginosa were tested for in vitro susceptibility to gentamicin, amikacin, tobramycin, netilmicin, kanamycin, streptomycin, cefotaxime, ceftriaxone, cefoperazone, ceftazidime, moxalactam, azlocillin, piperacillin and ticarcillin. Against 93 gentamicin-sensitive strains, the most active antibiotics were in descending order, ceftazidime, tobramycin, gentamicin, amikacin, and the ureidopenicillins. Against 77 gentamicin-resistant strains, only ceftazidime, amikacin and moxalactam had mode minimum inhibitory concentrations within achievable peak serum levels after standard therapeutic dosage. There was no correlation between cephalosporin resistance and aminoglycoside resistance except for cefoperazone, which, together with the ureidopenicillins and ticarcillin, showed marked decrease in activity against gentamicin-resistant strains.
Fulltext Effects of a pharmaceutical care model on medication adherence and glycemic control of people with type 2 diabetes

Chung WW, Chua SS, Lai PS, Chan SP

Patient Prefer Adherence, 2014;8:1185-94.
PMID: 25214772 DOI: 10.2147/PPA.S66619

Background: Diabetes mellitus is a lifelong chronic condition that requires self-management. Lifestyle modification and adherence to antidiabetes medications are the major determinants of therapeutic success in the management of diabetes.
Purpose: To assess the effects of a pharmaceutical care (PC) model on medication adherence and glycemic levels of people with type 2 diabetes mellitus.
Patients and methods: A total of 241 people with type 2 diabetes were recruited from a major teaching hospital in Malaysia and allocated at random to the control (n=121) or intervention (n=120) groups. Participants in the intervention group received PC from an experienced pharmacist, whereas those in the control group were provided the standard pharmacy service. Medication adherence was assessed using the Malaysian Medication Adherence Scale, and glycemic levels (glycated hemoglobin values and fasting blood glucose [FBG]) of participants were obtained at baseline and after 4, 8, and 12 months.
Results: At baseline, there were no significant differences in demographic data, medication adherence, and glycemic levels between participants in the control and intervention groups. However, statistically significant differences in FBG and glycated hemoglobin values were observed between the control and intervention groups at months 4, 8, and 12 after the provision of PC (median FBG, 9.0 versus 7.2 mmol/L [P<0.001]; median glycated hemoglobin level, 9.1% versus 8.0% [P0.001] at 12 months). Medication adherence was also significantly associated with the provision of PC, with a higher proportion in the intervention group than in the control group achieving it (75.0% versus 58.7%; P=0.007).
Conclusion: The provision of PC has positive effects on medication adherence as well as the glycemic control of people with type 2 diabetes. Therefore, the PC model used in this study should be duplicated in other health care settings for the benefit of more patients with type 2 diabetes.

Impact of pharmaceutical care on knowledge, quality of life and satisfaction of postmenopausal women with osteoporosis

Lai PS, Chua SS, Chan SP

Int J Clin Pharm, 2013 Aug;35(4):629-37.
PMID: 23677816 DOI: 10.1007/s11096-013-9784-x

BACKGROUND: This study describes the analysis of secondary outcomes from a previously published randomised controlled trial, which assessed the effects of pharmaceutical care on medication adherence, persistence and bone turnover markers. The main focus of this manuscript is the effect of the provision of pharmaceutical care on these secondary outcomes, and details on the design of the intervention provided, the osteoporosis care plan and materials used to deliver the intervention.
OBJECTIVES: To evaluate the effects of pharmaceutical care on knowledge, quality of life (QOL) and satisfaction of postmenopausal osteoporotic women prescribed bisphosphonates, and their associating factors.
SETTING: Randomised controlled trial, performed at an osteoporosis clinic of a tertiary hospital in Malaysia.
METHODS: Postmenopausal women diagnosed with osteoporosis (T-score ≤-2.5/lowtrauma fracture), just been prescribed weekly alendronate/risedronate were randomly allocated to receive intervention or standard care (controls). Intervention participants received a medication review, education on osteoporosis, risk factors, lifestyle modifications, goals of therapy, side effects and the importance of medication adherence at months 0, 3, 6 and 12.
MAIN OUTCOMES MEASURE: Knowledge, QOL and satisfaction.
RESULTS: A total of 198 postmenopausal osteoporotic women were recruited: intervention = 100 and control = 98. Intervention participants reported significantly higher knowledge scores at months 3 (72.50 vs. 62.50 %), 6 (75.00 vs. 65.00 %) and 12 (78.75 vs. 68.75 %) compared to control participants. QOL scores were also lower (which indicates better QOL) at months 3 (29.33 vs. 38.41), 6 (27.50 vs. 36.56) and 12 (27.53 vs. 37.56) compared to control participants. Similarly, satisfaction score was higher in intervention participants (93.67 vs. 84.83 %). More educated women, with back pain, who were provided pharmaceutical care had better knowledge levels. Similarly, older, more educated women, with previous falls and back pain tend to have poorer QOL, whilst women who exercised more frequently and were provided pharmaceutical care had better QOL. Satisfaction also increased as QOL increases and when provided pharmaceutical care.
CONCLUSION: The provision of pharmaceutical care improved knowledge, QOL and satisfaction in Malaysian postmenopausal osteoporotic women, showing that pharmacists have the potential to improve patients' overall bone health. Policymakers should consider placing a clinical pharmacist in the osteoporosis clinic to provide counselling to improve these outcomes.

The effect of mandatory generic substitution on the safety of alendronate and patients' adherence

Lai PS, Chua SS, Chong YH, Chan SP

Curr Med Res Opin, 2012 Aug;28(8):1347-55.
PMID: 22746354 DOI: 10.1185/03007995.2012.708326

Generic medicines are often used in public hospitals. However, data on the quality of generic alendronate, its efficacy, side-effects and medication adherence in clinical practice is scarce. Therefore, this study aimed to compare the side-effects and medication adherence of generic (apo-alendronate*) and proprietary alendronate (Fosamax†).

Lai PS, Chua SS, Chan SP

J Clin Pharm Ther, 2012 Oct;37(5):536-43.
PMID: 22380577 DOI: 10.1111/j.1365-2710.2012.01335.x

Pharmacists have been involved in providing comprehensive interventions to osteoporosis patients, but pharmaceutical care issues (PCIs) encountered during such interventions have not been well documented. Therefore, the aim of this study was to document PCIs encountered by post-menopausal osteoporotic women prescribed bisphosphonates.
Effects of pharmaceutical care on adherence and persistence to bisphosphonates in postmenopausal osteoporotic women

Lai PS, Chua SS, Chew YY, Chan SP

J Clin Pharm Ther, 2011 Oct;36(5):557-67.
PMID: 21916908 DOI: 10.1111/j.1365-2710.2010.01210.x

Studies have shown that comprehensive interventions by pharmacists can improve adherence and persistence to osteoporosis therapy, but the association between adherence and bone turnover markers (BTMs) has never been studied. Therefore, the aim of this study was to evaluate the effects of pharmaceutical care on medication adherence (and its effects on BTMs), as well as persistence of postmenopausal osteoporotic women to prescribed bisphosphonates.
The impact of pharmacist intervention on the use of activated vitamin D in a tertiary referral hospital in Malaysia

Siow JY, Lai PS, Chua SS, Chan SP

Int J Pharm Pract, 2009 Oct;17(5):305-11.
PMID: 20214273

In recent years, the usage of activated vitamin D (alpha-calcidol and calcitriol) in the University Malaya Medical Centre (UMMC) has escalated and this has put unnecessary burden on the hospital's limited health care budget. The main aim of this study was to determine the effects of a clinical pharmacist's intervention in reducing the inappropriate use of activated vitamin D.

Maturitas, 2008 Jun 20;60(2):122-30.
PMID: 18508210 DOI: 10.1016/j.maturitas.2008.04.006

OBJECTIVES: To design a valid and reliable questionnaire, the Malaysian Osteoporosis Knowledge Tool (MOKT), to assess the knowledge of postmenopausal osteoporotic women in Malaysia, on osteoporosis and its treatment.
METHODS: A 40-item instrument was designed and tested in this study. The scores ranged from 1 to 40, which were then converted into percentage. This was administered to 88 postmenopausal osteoporotic women who were taking alendronate (patient group) and 43 pharmacists (professional group). The MOKT was administered again to the patient group after 1 month.
RESULTS: Flesch reading ease was 57, which is satisfactory, while the mean difficulty factor+/-S.D. was 0.73+/-0.25, indicating that the MOKT is moderately easy. Internal consistency of the instrument was good with Cronbach's alpha=0.82. The test and retest scores showed no significant difference for 38 out of the 40 items, indicating that the questionnaire has achieved a stable reliability. Level of knowledge on osteoporosis and its treatment was good with a mean score+/-S.D. of 69.0+/-13.9 and 81.6+/-9.5 in the patient and professional group, respectively. The difference in knowledge scores between the two groups was statistically significant (p<0.001).
CONCLUSIONS: In conclusion, the 40-item questionnaire (MOKT) is a reliable and valid instrument for measuring knowledge on osteoporosis in the Malaysian setting. Therefore, it can be used to identify individuals in need of educational interventions and to assess the effectiveness of education efforts as part of osteoporosis management.
Fulltext The Malaysian Medication Adherence Scale (MALMAS): concurrent validity using a clinical measure among people with type 2 diabetes in Malaysia

Chung WW, Chua SS, Lai PS, Morisky DE

PLoS One, 2015;10(4):e0124275.
PMID: 25909363 DOI: 10.1371/journal.pone.0124275

Medication non-adherence is a prevalent problem worldwide but up to today, no gold standard is available to assess such behavior. This study was to evaluate the psychometric properties, particularly the concurrent validity of the English version of the Malaysian Medication Adherence Scale (MALMAS) among people with type 2 diabetes in Malaysia. Individuals with type 2 diabetes, aged 21 years and above, using at least one anti-diabetes agent and could communicate in English were recruited. The MALMAS was compared with the 8-item Morisky Medication Adherence Scale (MMAS-8) to assess its convergent validity while concurrent validity was evaluated based on the levels of glycated hemoglobin (HbA1C). Participants answered the MALMAS twice: at baseline and 4 weeks later. The study involved 136 participants. The MALMAS achieved acceptable internal consistency (Cronbach's alpha=0.565) and stable reliability as the test-retest scores showed fair correlation (Spearman's rho=0.412). The MALMAS has good correlation with the MMAS-8 (Spearman's rho=0.715). Participants who were adherent to their anti-diabetes medications had significantly lower median HbA1C values than those who were non-adherence (7.90 versus 8.55%, p=0.032). The odds of participants who were adherent to their medications achieving good glycemic control was 3.36 times (95% confidence interval: 1.09-10.37) of those who were non-adherence. This confirms the concurrent validity of the MALMAS. The sensitivity of the MALMAS was 88.9% while its specificity was 29.6%. The findings of this study further substantiates the reliability and validity of the MALMAS, in particular its concurrent validity and sensitivity for assessing medication adherence of people with type 2 diabetes in Malaysia.

Putting together the reports in this issue that come from a representation of the different countries in Asia presents an opportunity to share the unique story of the Asia Pacific Society of Human Genetics (APSHG), which has provided the authors of many of these articles. This paper, authored by the Past Presidents of the Society, shares glimpses of how medical genetics activities were first organized in the Asia Pacific region and provides interesting corollaries on how under-developed and developing countries in this part of the world had developed a unique network for exchange and sharing of expertise and resources. Although APSHG was formally registered as a Society in Singapore in 2006, the Society has its origins as far back as in the 1990s with members from different countries meeting informally, exchanging ideas, and collaborating. This treatise documents the story of the experiences of the Society and hopes it will provide inspiration on how members of a genetics community can foster and build a thriving environment to promote this field.
Fulltext The validity and reliability of the English version of the diabetes distress scale for type 2 diabetes patients in Malaysia

Chin YW, Lai PS, Chia YC

BMC Fam Pract, 2017 02 20;18(1):25.
PMID: 28219325 DOI: 10.1186/s12875-017-0601-9

BACKGROUND: Several disease specific instruments have been developed to identify and assess diabetes distress. In Malaysia, the Problem Areas in Diabetes Scale has been validated in Malay, but it does not have specific domains to assess the different areas of diabetes-related distress. Hence, we decided to use the Diabetes Distress Scale instead. To date, only the Malay version of the Diabetes Distress Scale has been validated in Malaysia. However, English is widely spoken by Malaysians, and is an important second language in Malaysia. Therefore, our aim was to determine the validity and reliability of the English version of the Diabetes Distress Scale among patients with type 2 diabetes in Malaysia.
METHODS: The Diabetes Distress Scale was administered to 114 patients with type 2 diabetes, who could understand English, at baseline and 4 weeks later, at a primary care clinic in Malaysia. To assess for convergent validity, the Depression Anxiety Stress Scale was administered at baseline. Discriminative validity was assessed by analysing the total diabetes distress scores of participants with poor (HbA1c > 7.0%) and good glycaemic control (HbA1c ≤ 7.0%).
RESULTS: The majority of our participants were male 65(57.0%), with a median duration of diabetes of 9.5 years. Exploratory factor analysis showed that the Diabetes Distress Scale had 4 subscales, as per the original Diabetes Distress Scale. The overall Cronbach's α was 0.920 (range = 0.784-0.859 for each subscale). The intraclass correlation ranged from 0.436 to 0.643 for test-retest. The Diabetes Distress Scale subscales were significantly correlated with the different subscales of the Depression Anxiety Stress Scale (spearman's rho range = 0.427-0.509, p
Isolated hyoid bone fracture in a child due to a fall

Chainchel Singh MK, Siew SF, Lai PS

Int J Pediatr Otorhinolaryngol, 2020 Dec;139:110443.
PMID: 33068949 DOI: 10.1016/j.ijporl.2020.110443

Hyoid bone fractures due to blunt trauma are rare accounting for only 0.002% of all head and neck fractures with most documented fractures being due to strangulation, hanging, motorcycle helmet straps, sports injuries and rarely as a complication of intubation. However, they are even rarer in the paediatric age group. We present a hyoid bone fracture in a two-year-old child as a result of a fall down three steps. Hyoid bone fractures though generally heal well with conservative treatment must be diagnosed early to avoid air way obstruction leading to morbidity and mortality.

Lai PS, Tan SY, Liew SM

Arch Sex Behav, 2016 Nov;45(8):2081-2089.
PMID: 27502351 DOI: 10.1007/s10508-016-0796-1

Sociocultural factors have been shown to be important influencers of sexual health and sexuality. Hence, the aim of our study was to explore the views and experiences of family medicine trainees regarding female sexual dysfunction (FSD) with a focus on the barriers and facilitators towards the initiation of conversation on this topic. A qualitative study design involving semi-structured focus group discussions (FGDs) was conducted with 19 family medicine trainees in Malaysia. The conceptual framework used was based on the Theory of Planned Behavior. Thematic approach was used to analyze the data. Participants perceived FSD as being uncommon and unimportant. According to our participants, patients often presented with indirect complaints, and doctors were not proactive in asking about FSD. Three main barriers were identified: doctor factors, perceived patient factors, and system factors. Lack of confidence, knowledge, experience, time, and embarrassment were the key barriers identified at the doctors' level. Lack of awareness, among patients regarding FSD, and local cultural and religious norms were the perceived patient barriers. System barriers were lack of time and privacy. Various facilitators, such as continuous medical education and public forums, were suggested as means to encourage family medicine trainees to initiate discussion on sexual matters during consultations. In conclusion, family medicine trainees found it difficult to initiate conversation on FSD with patients. Interventions to encourage conversation on FSD should target this and other identified barriers.
Fulltext The development and validation of the advance care planning questionnaire in Malaysia

Lai PS, Mohd Mudri S, Chinna K, Othman S

BMC Med Ethics, 2016 10 18;17(1):61.
PMID: 27756366

BACKGROUND: Advance care planning is a voluntary process whereby individual preferences, values and beliefs are used to aid a person in planning for end-of-life care. Currently, there is no local instrument to assess an individual's awareness and attitude towards advance care planning. This study aimed to develop an Advance Care Planning Questionnaire and to determine its validity and reliability among older people in Malaysia.

METHODS: The Advance Care Planning Questionnaire was developed based on literature review. Face and content validity was verified by an expert panel, and piloted among 15 participants. Our study was conducted from October 2013 to February 2014, at an urban primary care clinic in Malaysia. Included were those aged >50 years, who could understand English. A retest was conducted 2 weeks after the first administration.

RESULTS: Participants from the pilot study did not encounter any problems in answering the Advance Care Planning Questionnaire. Hence, no further modifications were made. Flesch reading ease was 71. The final version of the Advance Care Planning Questionnaire consists of 66 items: 30 items were measured on a nominal scale, whilst 36 items were measured on a Likert-like scale; of which we were only able to validate 22 items, as the remaining 14 items were descriptive in nature. A total of 245 eligible participants were approached; of which 230 agreed to participate (response rate = 93.9 %). Factor analysis on the 22 items measured on a Likert-scale revealed four domains: "feelings regarding advance care planning", "justifications for advance care planning", "justifications for not having advance care planning: fate and religion", and "justifications for not having advance care planning: avoid thinking about death". The Cronbach's alpha values for items each domain ranged from 0.637-0.915. In test-retest, kappa values ranged from 0.738-0.947.

CONCLUSIONS: The final Advance Care Planning Questionnaire consisted of 63 items and 4 domains. It was found to be a valid and reliable instrument to assess the awareness and attitude of older people in Malaysia towards advance care planning.
Management of unidentified and unclaimed bodies: a comparison of model from four countries in the Asia Pacific Region

Khoo LS, Lai PS, Siew SF, Ibrahim MA

Forensic Sci Med Pathol, 2023 Jul 31.
PMID: 37523136 DOI: 10.1007/s12024-023-00683-6

Managing mass fatality incidents or disasters involving multiple deaths are not uncommon among forensic practitioners. In fact, management of unidentified or unknown bodies is also a vital component of the day-to-day mortuary work practice. The unidentified and subsequently unclaimed bodies have always been a "silent mass disaster," a problem that needs to be tackled within the forensic community and raises the global issue of ethics, law, and human rights. Unidentified bodies' in Malaysia make up an average of 4.02% of all death cases where a total postmortem examination was performed which is comparable with other developing countries within 4-10% which can go up to 25%. Moreover, unstandardized procedures in all mortuaries in different states and districts in Malaysia have worsened the scenario even with guidelines in place. This study aims to address the issues surrounding unidentified and unclaimed bodies including body disposal from a social and legal perspective using case study methodology by comparing four different countries in the Asia Pacific Region through document analysis and interview methods. One of the major findings is evident in 3 out of the 4 models, whereby there is a considerable gap in consolidating the missing person report and information to match with the unidentified bodies received in forensic institutions in an attempt to enhance the identification process which ultimately intends as a closure for the family members. It is also timely to think out of the box beyond dental records and DNA profiling to improve the identification rate for skeletonized remains through means of anthropology biometrics comparison. With the limited literature published surrounding this domain, it is hoped that the suggestions and recommendations to standardize the management of unidentified and unclaimed bodies can benefit many forensic institutions and public mortuaries in this region.
Fulltext Validation of the diabetes, hypertension and hyperlipidemia (DHL) knowledge instrument in Malaysia

Lai PS, Chua SS, Tan CH, Chan SP

BMC Med Res Methodol, 2012 Feb 24;12:18.
PMID: 22361093 DOI: 10.1186/1471-2288-12-18

BACKGROUND: Patient's knowledge on diabetes, hypertension and hyperlipidaemia and its medications can be used as one of the outcome measures to assess the effectiveness of educational intervention. To date, no such instrument has been validated in Malaysia. Therefore, the aim of this study was to evaluate the validity and reliability of the Diabetes, Hypertension and Hyperlipidemia (DHL) knowledge instrument for assessing the knowledge of patients with type 2 diabetes in Malaysia.
METHODS: A 28-item instrument which comprised of 5 domains: diabetes, hypertension, hyperlipidemia, medications and general issues was designed and tested. One point was given for every correct answer, whilst zero was given for incorrect answers. Scores ranged from 0 to 28, which were then converted into percentage. This was administered to 77 patients with type 2 diabetes in a tertiary hospital, who were on medication(s) for diabetes and who could understand English (patient group), and to 40 pharmacists (professional group). The DHL knowledge instrument was administered again to the patient group after one month. Excluded were patients less than 18 years old.
RESULTS: Flesch reading ease was 60, which is satisfactory, while the mean difficulty factor(SD) was 0.74(0.21), indicating that DHL knowledge instrument was moderately easy. Internal consistency of the instrument was good, with Cronbach's α = 0.791. The test-retest scores showed no significant difference for 26 out of the 28 items, indicating that the questionnaire has achieved stable reliability. The overall mean(SD) knowledge scores was significantly different between the patient and professional groups [74.35(14.88) versus 93.84(6.47), p < 0.001]. This means that the DHL knowledge instrument could differentiate the knowledge levels of participants. The DHL knowledge instrument shows similar psychometric properties as other validated questionnaires.
CONCLUSIONS: The DHL knowledge instrument shows good promise to be adopted as an instrument for assessing diabetic patients' knowledge concerning their disease conditions and medications in Malaysia.
Fulltext A qualitative study of community pharmacists' opinions on the provision of osteoporosis disease state management services in Malaysia

Nik J, Lai PS, Ng CJ, Emmerton L

BMC Health Serv Res, 2016 08 30;16:448.
PMID: 27577560 DOI: 10.1186/s12913-016-1686-x

BACKGROUND: Osteoporosis has significant impact on healthcare costs and quality of life. Amongst the models for collaborative disease state management services published internationally, there is sparse evidence regarding the role of community pharmacists in the provision of osteoporosis care. Hence, the aim of our study was to explore community pharmacists' opinions (including the barriers and facilitators) and scope of osteoporosis disease state management services by community pharmacists in Malaysia, informing a vision for developing these services.

METHODS: Semi-structured individual interviews and focus groups discussions were conducted with community pharmacists from October 2013 to July 2014. Three trained researchers interviewed the participants. Interviews were recorded and transcribed verbatim. Data were analyzed thematically using an interpretative description approach.

RESULTS: Nineteen community pharmacists with 1-23 years of experience were recruited (in depth interviews: n = 9; focus group discussions: n = 10). These participants reflected on their experience with osteoporosis-related enquiries, which included medication counseling, bone density screening and referral of at-risk patients. Key barriers were the lack of numerous factors: public awareness of osteoporosis, accurate osteoporosis screening tools for community pharmacists, pharmacists' knowledge on osteoporosis disease and medications, time to counsel patients about bone health, collaboration between pharmacists and doctors, and support from the government and professional body. The pharmacists wanted more continuing education on osteoporosis, osteoporosis awareness campaigns, a simple, unbiased osteoporosis education material, and inter-professional collaboration practices with doctors, and pharmacists' reimbursement for osteoporosis care.

CONCLUSIONS: The involvement of community pharmacists in the provision of osteoporosis disease state management was minimal. Only ad-hoc counseling on osteoporosis prevention was performed by community pharmacists. Development and trial of collaborative osteoporosis disease state management services in community pharmacy could be facilitated by training, support and remuneration.

PMID: 25648757 DOI: 10.1007/s11136-015-0933-7

PURPOSE: To assess the validity and reliability of the Malay version of the Quality of Life (QOL) Questionnaire of the European Foundation for Osteoporosis (QUALEFFO-41) in Malaysia.
METHODS: The QUALEFFO-41 was translated from English to Malay and administered to 215 post-menopausal osteoporotic women ≥50 years who could understand Malay, at baseline and 4 weeks. The SF-36 was administered at baseline to assess convergent validity. To assess discriminative validity, patients with and without back pain were recruited.
RESULTS: Confirmatory factor analysis showed that the QUALEFFO-41 had five domains. Good internal consistency was seen in all domains (0.752-0.925) except for the social activity domain (0.692). Test-retest reliability showed adequate correlation for all items (0.752-0.964, p < 0.001). Patients with back pain had significantly worse QOL compared with those without (back pain = 42.2 ± 10.9, no back pain = 33.3 ± 8.9; p < 0.001). The total QUALEFFO-41 score and the SF-36 physical and mental composite scores were significantly correlated (-0.636 and -0.529, p < 0.001, respectively).
CONCLUSIONS: The Malay version of the QUALEFFO-41 was found to be a reliable and valid instrument to evaluate the QOL of osteoporotic patients in Malaysia. To enable the QUALEFFO-41 to be used in a multiracial population, further studies should look into validating other versions of the QUALEFFO-41 in Malaysia.
